coordinator-mode

coordinator-mode is a skill for Claude Code from sefaertunc/Worclaude. It costs 17 tokens per session (820 once invoked), scanned A, original, MIT.

A set of patterns for splitting larger coding tasks among several software agents, with one agent coordinating the work. It covers parallel research, implementation, and checking the results.

In plain words
What is it for?
Use it to plan multi-agent work, write prompts for worker agents, combine their findings, assign implementation tasks, and run verification alongside development.
Why use it?
It helps when separate parts of a task can be done at the same time, while avoiding coordination overhead for small or strictly sequential work.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

coordinator-mode scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Coordinator Mode

When to Use Multi-Agent Coordination

Use coordinator patterns when:

  • A task has independent research + implementation phases
  • Multiple file areas can be worked on in parallel
  • Verification should run alongside implementation
  • You need to synthesize findings before directing follow-up work

Don't use coordinator patterns when:

  • The task is small enough for one session
  • Steps are strictly sequential with no parallelism
  • The overhead of coordination exceeds the work itself

Phase-Based Workflow

Most coordinated tasks follow four phases:

Phase Who Purpose
Research Workers (parallel) Investigate codebase, find files, understand problem
Synthesis You (coordinator) Read findings, understand the problem, craft implementation specs
Implementation Workers Make targeted changes per spec, commit
Verification Workers Test changes work, try to break them

The synthesis phase is the coordinator's most important job. When workers report research findings, you must understand them before directing follow-up work. Read the findings. Identify the approach. Then write a prompt that proves you understood by including specific file paths, line numbers, and exactly what to change.

Never write "based on your findings" or "based on the research." These phrases delegate understanding to the worker instead of doing it yourself.

Worker Prompt Best Practices

Workers cannot see your conversation. Every prompt must be self-contained:

Good — synthesized spec: "Fix the null pointer in src/auth/validate.ts:42. The user field is undefined when sessions expire but the token is still cached. Add a null check before user.id access. Commit and report the hash."

Bad — lazy delegation: "Based on your findings, fix the auth bug." "The worker found an issue. Please fix it."

Purpose Statement

Include a brief purpose so workers calibrate depth:

  • "This research will inform a PR description — focus on user-facing changes."
  • "I need this to plan an implementation — report file paths, line numbers, and type signatures."
  • "This is a quick check before we merge — just verify the happy path."

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

coordinator-mode is a skill published in the GitHub repository sefaertunc/Worclaude (4 stars, last pushed 27d ago), licensed MIT. It adds 17 tokens to every session and 820 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
